The point of this exercise is a form of dollar cost averaging, being consistent, and doing this every day or every month. For most people, they get paid twice a month, so they can do the buying every 2 weeks. Something the equivalent of maybe $15 every pay day, which is close to a dollar a day.
People should be saving more, and starting now (or as early as they can) going forward for the next 20 to 30 to 40 years. By the time they retire, they should have at least a million worth, assuming they never touched their coins.
This applies as well with traditional investments and is actually a very basic retirement plan, also safe and sound and more or less proven.
Saving bitcoin is a big challenge I try saving a lot of people as soon as I can but when it comes to emergency most of the time I will spend my savings and then going to be disappointed in the end.
I think it will be a great feature to have in a bitcoin wallet if we could have a wallet that has a timer when we cannot withdraw the bitcoin if the timer is still running. That would make saving bitcoin easy

i start investing 10% of my monthly wages in Bitcoin and 3 other currencies more than a year now,and i can relate on this story as i am now in good profit(though i am still holding my coins up to now)
i still have no plans of getting out until my target Prices reached.
i trust crypto more than my Banks but of course i only limit my investments for my own safeties.though if this Halving Gives more than 2017 ?i will consider taking out my investments and wait when market falls down again to re invest.
For sure it is still not a good time to withdraw your investment, I just invest in bitcoin most of the time when the market goes down because I think it was more profitable when the market recovers in the end.
